Description

HCatContext is a container for a configuration that is globally accessible both on the FE & BE. Its purpose is to simplify enabling optional functionality.

When I originally added this class I didn't use an enum, not knowing its the recommended way of doing singletons in java. Since we haven't make a release with this class I think we should change it now to the "Right Way" before it gets much use.

I also added annotations showing the intended audience, and added some pretty good javadocs.
